CHARLES O. SCHMITT,

IMPROVE OF NEV YORK, N. Y.

D CHAIR- Specilicnlion forming part of Letters Patent No. 58,682, datedOctober 9, 1866.

To all whom it may concern:

Beit known that I, C. C. SCHMITT, of the city, county, and State of NewYork, have invented a new and useful Improvement in Chairs; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming a part of this specification.

The present invention consists principally in so arranging orconstructing the frames of that class of chairs having the material usedfor its seat and back made of a continuous strip or piece of cloth orother suit-able matc- -rial, that while the back of the chair can beadjusted to any desired inclination, whether more or less, from avertical to a horizontal plane, or nearly so, the strip of cloth orother material constituting the back and seat of the chair can be letout or taken up to suit the inclination to which the back of themchairis adjusted and set, as will be obvious from the following detaildescription of the saine, reference being had to the accompanying plateof drawings, in which- Figure 1 is a front view and elevation of a chairmade according to the present invention, and Fig. 2 a central verticalsection taken in the plane of the line a: Fig. l.

A in the drawings represents the chair, which consists of two frames,Band G, hinged or pivoted together at D, the one B within the other, sothat they can be opened from and closed upon eachv other at pleasure,with the lower portions of the two frames, or that below the point D ofpivoting, constituting the legs of the chair, while the upper portionofthe two frames constitute, the one,B, the back, and the other, C, theseat, as embraced by the space E, between .the upper end of the saidframe C and the other or back frame B, when opened from each, as shownin Fig. 1 of the drawings.

At the upper end F of the back-frame C a roller or round, G, is secured,to which is secured one end of a strip or piece ot' cloth, H, or othersuitable material ordinarily employed for upholstering or coveringchairs or other articles of furniture, the other end being secured to aroller, I, extending across and between the upper ends of the frame C,to which it is hung so as to be revolved, and thus enable the said clothto be wound around and upon the same, or unwound therefrom, according asit may be desired to lengthen or shorten the said cloth, to adjust it tothe inclination of the back-frame, as will be hereinafter explained.

This roller-I at one end is provided with a ratcliet-wheel, J, withwhich a spring-pawl, K, engages, hung in and to the arm-post L ot' thechair, hung so as to swing thereon at a corresponding end to that atwhich the said ratchet is secured; this pawl being pivoted to engagewith the said ratchet so as to hold the roller in position and preventthe cloth wound upon it from unwinding.

Mis a leverhnn g in the arm-post L, in proper position. to raise thespring-pawl K from the ratchet-wheel, an-d thus disengage it whendesired to unwind the cloth; N, an arm-post hung to the opposite end ofthe chair-frame C to that where the arm-post L is secured, to each ofwhich arm-posts N and L one end of belts O are hung, that at theiropposite ends are secured to the chairback frame B, and are both soarranged that by means of buckles l? they can be lengthened andshortened at pleasure.

To the rear side of the chair-back frame B ratchet or toothed bars Q aresecured, extend ing from the point D, at which such frame is pivoted, tothe other frame upward a short distance, with which ratchet-bars across-bar, S, by means of an elastic loop, T, is so hung to the centerround, U, of the chair that it may be made to engage with or bedisengaged from the said ratchet-bars at pleasure; the said crossbar S,when engaged with the teeth of the said ratchet-bars firmly holding theback frame in whatever positionit may be set or adj usted, whether moreor less inclined.

From the above description it is plain to be seen that by theconstruction of the chair its back can be adjusted and set at anyinclination desiredfwhether more or less, when changing the length ofthe strip of cloth to /correspond thereto-that is, either lengthen orshorten it more or less by unwinding it from or winding it upon theroller, the seat and back of the chair can be properly adjusted to theinclination of the chair-back, to render the frame that it can belengthened or shortened,

chair easy and comfortable in use. in the manner herein specified, andfor the Having thus described my invention, l claim purpose set forth.
